My friend brought me his dead machine. The following parts have tested good. GTX 970, SSD, mechanical hard drive and the DDR4. The following items I could not test. CPU as I don't have a LGA 1151 board, motherboard as I don't have another cpu to swap in, proprietary power brick also. My assumption is the board is more than likely the culprit. I think the power brick is fine because it powers on and the hard drive activity light sporadically works when I try to boot it up. No video signal whatsoever. 99.9% the cpu is good I would think. I am pretty sure the cpu is an I7-6700. My plan would be to get him a micro-atx board and build him a real pc. Anyone have any suggestions?
